Developer Naughty Dog will be adding in two new multiplayer maps for free to their remastered version of The Last of Us, noting the gesture of goodwill "in appreciation for all of your continued patience as we work to resolve the matchmaking issues."

PlayStation 4 users have been made to endure long waits while to connect to the game's online Factions mode - an issue that the developer is now working with other PlayStation teams to try and fix.

"Over the last couple of weeks, we have deployed LiveUpdates and Patch 1.02, which have resulted in some significant improvements, but there is still more to be done to reduce the matchmaking wait times," Naughty Dog explained via its official site.

"We've discovered that the most significant improvements may come from working with other teams at PlayStation to make updates to some of the existing matchmaking libraries. Our current estimate is on the short side of weeks, rather than months."
